1. Photography assisted in the study of solar prominences , granulation and spectroscopy. 2. They often follow solar flares and are normally present during a solar prominence eruption. 3. The solar physics researchers perform solar prominence and chromosphere features observations in the H-alpha line. 4. Another early observation was of solar prominences , described in 1185 in the Russian Chronicle of Novgorod. 5. The eclipse is mentioned in the 14th-century Laurentian Chronicle with the first detailed description of solar prominences . 6. Its polar field is, whereas the field is typically in features on the Sun called sunspots and in solar prominences . 7. He was the first person to demonstrate a correlation between the number of solar prominences and the number of sun spots. 8. D . M . Rust and A . Kumar were particularly active in using magnetic helicity and relaxation to study solar prominences . 9. He did important spectrographic work in astronomy, inventing his well-known star-spectroscope in 1875 and observing solar prominences . 10. F�nyi Gyula was noted for his observations of the Sun, including spectroscopic studies of solar prominences , as well as sun spots.
